Indigo Construction installs egress windows in basement and lower-level spaces to meet building code requirements for safe emergency exit and to bring natural light into areas used as bedrooms or living spaces in Sioux Falls, Madison, Flandreau, and surrounding areas. You need this service when finishing a basement for habitable use, when converting existing basement space into a bedroom, or when selling or refinancing a home and an inspector identifies the absence of compliant egress as a code violation. The installation involves cutting through the foundation wall, excavating an exterior window well, installing the window unit, and finishing both the exterior and interior surfaces.

Egress windows must meet minimum size requirements for opening width, height, and sill height to allow a person to exit quickly in an emergency. The window well outside is sized to provide clearance and often includes a drain to prevent water accumulation. Interior work includes framing the opening, insulating around the window, installing drywall, and finishing the sill and trim so the window looks intentional and matches the rest of the room.

If you are finishing a basement or need to bring a lower-level bedroom up to code, reach out to discuss window sizing, placement, and how the installation integrates with your project timeline.

The process starts with marking the exterior and interior locations, cutting through the concrete or block foundation wall with a concrete saw, and excavating soil outside to create space for the window well. You will see the window unit installed with proper flashing and sealing to prevent water intrusion, followed by backfill around the well and gravel at the base for drainage. Interior framing supports the window, and drywall is applied, taped, and finished flush with the surrounding wall.

Once the work is complete, you will notice a functional window that opens fully, a well-lit basement space that no longer feels enclosed, and an exit path that meets code requirements for bedroom occupancy. Indigo Construction handles the full scope from cutting to final interior finish, so the installation is ready for inspection and use without additional coordination.

The work does not include permits, which are typically required and obtained before installation begins. Installation time for a single egress window is usually completed within two to three days, depending on wall thickness and site conditions.

Questions often focus on code requirements, placement, and how the installation affects the interior and exterior of the home.

What size does an egress window need to be to meet code?

The window must have a minimum net clear opening of 5.7 square feet, with a minimum width of 20 inches, minimum height of 24 inches, and a sill height no more than 44 inches above the floor.

How deep does the window well need to be?

The well extends from the bottom of the window opening down to below-grade level, typically 3 to 4 feet deep, and must include a ladder or steps if the depth exceeds 44 inches.

Why is drainage important in a window well?

Without proper drainage, water collects at the base of the well and can seep through the window or foundation wall, causing leaks and moisture damage in the basement.

When is an egress window required in a basement?

Building codes require egress windows in any basement room used as a bedroom or habitable space, and inspectors check for compliance during remodels, sales, and occupancy permits.

What happens to the soil and concrete removed during installation?

Concrete is hauled away as construction debris, and excess soil is either spread on the property if grading allows or removed as part of the cleanup process.
